This
automotive "how-to" guide was specifically written to assist owners
of the 2003 to 2008 Toyota Corolla in replacing the CR2032 3V coin
battery in the key fob remote control.

Owners of other Toyota vehicles such as
the Camry, 4Runner, Matrix, Yaris, Prius, Venza, Avalon, FJ Cruiser,
Sienna, RAV4, Highlander, Sequoia, Tacoma and Tundra equipped with
similar keyless entry systems may also find this guide to be
helpful.

The only tool needed to complete this
battery change is a small flathead screwdriver. A small coin or
butter knife may also work if you don't have a screwdriver handy.

A replacement CR 2032 3V coin or
"watch" battery can be purchased at a variety of stores such as CVS,
Radio Shack, or Wal-Mart. I prefer to buy coin batteries on eBay
where a 5 pack of CR2032 cells can be bought for $0.99.

To pop open a
Toyota key fob remote control, locate the small notch or cutout area at the
top edge of the unit above the "Lock" button. Insert the small flathead
screwdriver into the recessed slot and turn the screwdriver to separate the
top and bottom halves.

When I popped open
the Toyota key fob, the buttons went flying across my desk. The battery is
located on the underside of the rubber wrapped remote control unit. To
remove the battery, gently pry it out with the small flathead screwdriver.

Push in a new
CR2032 battery with the top "+" side facing towards you. Then turn over the
remote unit, place the "Lock" and "Unlock" buttons on top and cover them
with the top of the key fob remote. Turn the unit over again and place the
bottom of the remote on top with the red "Panic" button facing up. Then snap
together the two halves and re-attach the key ring.
